INFLUENCE IN THE FEVERS OF INDIA, &C. II 



and although the lowest degree of this power act- 

 ing on paroxysmal dispositions in a high state of 

 propensity, may happen to produce febrile pa- 

 roxysms at an unusual period, such instances, 

 though apparently exceptions, are no argument 

 against the truth or principles of the general law : 

 but are consistent with it in every respect. 



Combining therefore the operation of the princi- 

 ples we have obtained from this analysis, we arc 

 enabled to construct a theorem, which serves to 

 explain in a new, but satisfactory manner, the 

 whole class of febrile diseases. 



THEOREM. 



TJie fluctuating force of sol-lunar influence coinciding 

 and cG-ope?^ating in all its various stages and de- 

 grees, zcith the various modipcations of the pa- 

 roxysmal disposition, excites jebrile pai^oxysms to 

 attack en all the days of the neaps and springs, 

 and supports and reiterates them, according to va- 

 rious types, until the commencement of diflh^ent 

 neaps ; at zvhich junctures the maturity of the cri- 

 tical disposition happening to concur xdth the pe- 

 riodical decline oj sol-lunar infuence, these pa- 

 roxysms then subside and come to a termination or 

 crisis: and thus J or m different successions of pa- 

 roxysms constituting fevei's of various length or 

 duration. 



It has been observed, respecting the various 

 forms of durations, that some are apt to occur 

 more frequently tlian others. To searcli for a solu- 

 tion of this question amidst the chaos of the incor- 

 rect and mutilated history that has been accumu- 

 lated on the subject of fevers, would be unsatisfac- 

 tory and useless. It will be far more prciitabie to
